Research On Multi Objective Group Decision Making For Load Forecasting And Distribution Network Planning In Baoding New District

Urban distribution network power system as an important part of,for the rational integration of various resources,power quality guarantee and promotion of an for the economic development of the region has a pivotal role,so rational,science,improve the distribution network planning is particularly important.With the rapid development of economy,original distribution network construction far behind the pace of development,to a certain extent and even restricted the development of power system,thereby affecting the prosperity and development of the economy,in order to meet the Baoding area to develop economy of electric load demand,and resource integration of the objective and the area of distribution network of scientific and rational planning and transformation,at the same time,the scientific and effective decision-making of power grid planning scheme is very necessary.On the one hand to the effectiveness of the verification planning project,on the other hand can through decision research found the problems existing in the distribution network planning project and provide an important reference in the distribution network planning project.Power load forecasting is the foundation and core of power supply planning,and the power load forecasting is the basic work of urban power network planning,which plays a key role in the quality of urban power network planning.So firstly the Baoding new power load of scientific research analysis,mainly uses the "district load density index method" of Baoding new power load forecasting,by predicting the long-term and intermediate in the load,power load of different periods.Secondly,in Baoding area general situation of power supply,power supply construction situation were analysis,get the problems existing in the present distribution networks of various voltage levels,combined with these problems and characteristics of the new grid,Baoding new distribution network planning project involves stakeholders are analyzed,and the needs of their own interests,in order to build a multi-objective group decision making evaluation index,is proposed based on entropy weight theory of distribution network planning multi-objective group decision model.The model is applied to the new district distribution network planning,the results show that the Baoding new district distribution network planning program to meet the overall interests of the parties,so the plan is more reasonable and scientific.
